Question 986449
C=7.5x+10,000
R=12x+12,000
12x=7.5x+22000, because they are equal when they breakeven, but there must be profit of 12,000
4.5x=22,000
x=4888.99 or 4889.
The revenue must be 22,000, but you can't divide that by 7.5
;
Set up the Cost function 10,000 fixed +7.5 x variable
Set up the Revenue function 12x.
At the breakeven point, the two are equal. When there is profit, that goes into the revenue function, and one solves accordingly.
